C# console application

I'm extremely new to C# and having a very hard time with this one. Any and all help is greatly appreciated! The more detailed the help the better because I'm pretty lost on this one.

Write a C# console application for a furniture company. Ask the user to choose P for pine, O for oak, and M for mahogany. Show the price of a table manufactured with the chosen wood. Pine tables cost $100, oak tables cost $225, and mahogany tables cost $310. If the user enters something other than P, O or M, set the price to $0. Save your program as Furniture.cs.
